COMPRESSIBLE TUBE.

SPECIFICATION forming part of Letters Patent No. 62;,5'73, dated March21, 1899. Application filed June 18,1898- Serial No. 683,877. (Nomodel.)

To all whom it may concern.-

Be it known that I, THEODORE Y. KINNE, a citizen of the United States,residing in Paterson, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Compressible Tubes; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to improvements in compressible tubes madeof ductile and impervious metal and which are usually,

provided with small discharge-outlets adapted to be closed byscrew-threaded capsand have their opposite ends folded and pressedtogether. Whenever the contents of said tubes is to be discharged,(after the screw-threaded caps have been removed,) the opposite orfolded ends are compressed. These tubes are generally used for paints,dentifrices, surgical dressings, &c., and especially when used forsurgical dressings are sterilized, together with said dressing, so as torender said dressing perfectly antiseptic to thus obviate the danger ofinoculating diseases to patients treated with it or to persons handlingthe same.

There are a number of surgical dressings or preparations which containvarious salts of metals-such as, for instance, salts of 'mercury-and itis an established fact that such preparations are being quicklydecomposed when put up in such compressible tubes, (generally made oflead or analogous ductile metals, compositions, or alloys,) andaccordingly such dressings or preparations have to-be put up inporcelain or glass jars or wooden boxes.

The object of this invention is-to overcome the objections abovereferred to and to provide a compressible tube for the reception ofsurgical dressings, &c., and by the use of which the said surgicaldressing cannot be afiected or decomposed by the metal or alloy of whichthe said tube is made. 4

The invention consists in the improved compressible tube havingits-interior wall or surface coated with a preparation indifferent totheaction of the metal or alloy of which the tube is made and alsoindifferent to the action of the preparation or dressing contained insaid tube, substantially as will be time is poured out.

hereinafter more fully described and finally embodied in .the clauses ofthe claim.

Figure 1 is a side elevation of my improved compressible tubev closedand partly in section; and Fig. 2, a front elevation of Fig. 1,

the inlet end being unfolded. e 1

is provided with a thin layer or coating j,

which coating consists of collodion to' which has-been added asmallquantityv of castoroil and balsam fir.

The collodion is prepared by mixing onehalf gallon of other withone-half gallon of alcohol and adding four and one-half ounces ofpyroxylin. To one gallon of said collodion is added from two to threeper cent. castoroil and from one to two per cent.- balsam fir.

For the purpose of coating the tubes the same are slightly heated andwhile warm are filled with the solution above referred to,,

which after remaining in said tubes a short A certain amount of thesolution adheres to the interior surface of the tubes and after theether and. alcohol has evaporated forms a thin layer or coating which isimpervious and indiiferent to the action of the metal of which the tubesare, made and also indifierent to the various surgical dressings, &c.,placed in said tubes. It must be remarked that .the said coating isnicely adapted in every particular to the purpose for which it isintended, being ductile, pliable, or flexible with and adhesive to thesurface of the tube, so as to easily bend with the latter withoutcracking or breaking and without being detached from or blistered onsaid surface and being practically una'ifected by the temperature whichis necessary in the process of sterilization.

For the purpose of completely expelling the I I air from the interior ofthe tubewhen the latter is being filled and the open end closed orfolded a small pin-hole g is provided form the wall of thetube, near itsopen end, and after said open end is closed-that is to say,

is compressed and'folded together- -the air which still may haveremained in the tube is discharged through said small pin-hole, and thelatter is then afterward closed by the folded or compressed portion ofthe tube.

I do not intend to limit myself to the coating solution above described,as other solutions may-be used advantageously to separate the dressingor preparation from its retaining-tubes; but

What I claim as new, and desire to secure by Letters Patent, is-- I 1. Acompressible tube composed of ductile and impervious metal having itsinterior surface or wall provided with a flexible, or pliable coating orlining and having near its inlet-opening a pin-hole or vent,substantially as described.

2. A compressible tube of ductile and impervious metal having itsinterior surface coated with a solution of collodion, castor-oil andbalsam-fir, and provided near its inletopening with a vent or pin-hole,substantially May, 1898.
